Homemade Transformers movies might be the best kind of Transformers movies, and YouTuber Harris Loureiro’s short proves it. In his “Attack on Giant” short, he used a giant Optimus Prime to battle a fleet of Constructicons. Loureiro spent a month editing his footage and adding special effects and sound. It may not have the budget of a Hollywood Transformers movie, but the stop motion short makes up for it with heart.
